| Regional ecosystem | 12.9-10.22 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Palustrine |
| Biodiversity status | Of concern |
| Subregion | 9, (4), (3) |
| Estimated extent1 | Pre-clearing 2000 ha; Remnant 2021 1000 ha |
| Short description | Closed sedgeland and/or shrubland on sedimentary rocks. Generally coastal |
| Structure code | Sedgeland |
| Description | Closed sedgeland to heathland with emergent trees. Characteristic species include Schoenus brevifolius and/or Machaerina juncea and/or Banksia robur and/or Melaleuca nodosa. Sometimes grading into Banksia aemula woodland on rises. Usually occurs on lower slopes subject to periodic water logging on Cainozoic and Mesozoic sediments. Palustrine. (BVG1M: 34f). |

| Protected areas | Great Sandy NP, Noosa NP, Glass House Mountains NP, Maroochy River CP |
| Special values | 12.9-10.22: Habitat for near threatened species Melaleuca cheelii. |
| Fire management guidelines | SEASON: Late summer to winter. INTENSITY: Moderate (to high; due to the inherent characteristics of highly flammable vegetation). INTERVAL: 8-20 years. INTERVAL_MIN: 8. INTERVAL_MAX: 20. STRATEGY: Aim for a burn mosaic of 40-80%. Ensure planned burn conditions are conducive to maintaining integrity of the landscape (i.e., use good soil moisture, recent rainfall and standing water on the ground). ISSUES: Intervals at the upper end (12-20 years) of the recommended regime may be desirable to counteract detrimental impacts of a high intensity fire over 100% of landscape. This vegetation often contains obligate seed regenerating species and as such, the application of frequent fire may reduce species richness if the intervals between fire are not sufficient for plants to produce seed. |
| Comments | 12.9-10.22: Under threat of becoming rare locally in some parts of the bioregion. |
